A stock room worker pushes a box with mass 11.2 kg on a horizontal surface with a constant speed of 4.50 m/s. The coefficient of kinetic friction between the box and the surface is 0.25. a) What horizontal force must be applied by the worker to maintain the motion? b) If the force calculated in parts (a) is removed, how far does the box slide before coming to rest
*I really don't know how to get started. I have done lots of the homework, but this one (and a couple of others) are really giving me PROBLEMS.* A stockroom worker pushes a box with a mass 10.5 kg on a horizontal surface with a
a worker pushes a 7kg shipping box along a roller track. assume friction is small enough to be ignored because of the rollers. the worker's push is 25 N directed down and to the right at an angle of 20 degrees. 1. determine the
a worker pushes a box with a horizontal force of 50 N over a level distance of 5m. If a frictional force of 43 N acts on the box in a direction opposite to that of the worker, what was the net work done to the box?
Two boxes (b1 = 23 kg and b2 = 57 kg) are being pushed across a horizontal frictionless surface, as the drawing shows. The 48-N pushing force is horizontal and is applied to the 23-kg box, which in turn pushes against the 57-kg
(Please put the resulting figures and Thanks)))) a man pushes a box of mass 5 kg in a horizontal direction by 10 N force on the surface through a distance of 5m if the cofficien of kinetic friction is 0.2 the total work done on
A box of mass 50.0 kg is connected to a second box with a mass of 54.0 kg. Both are sitting on a horizontal surface and the coefficient of kinetic friction between the surface and each box is 0.51. If the second box is pulled away
